If a fuse that is responsible for supplying power to the electric window on the driver's side and the turn signals has blown, it could result in the window stopping working and the turn signals functioning intermittently or not at all. To troubleshoot the issue, you can check the fuse box and replace any blown fuses with fuses of the same amperage rating. Additionally, it's a good idea to inspect the wiring and connections related to the electric window and turn signals to make sure there are no loose or damaged components that could be causing the problem. If the issue persists after replacing the blown fuse, it's recommended to seek the assistance of a qualified auto electrician for further diagnosis and repairs.
